SPECIFICATION forming part of Letters Patent No. 605,275, dated June 7, 1898.

Application filed August 6, 1897. Serial No. 647,316. (No model.)

To all whom it may concern:

Be it known that we, TALBOT (J. DEXTER,

of Pearl River, in the county of Rockland,

and J AMEs J. PARKER, of Brooklyn, in the county of Kings, in the State Of New York, have invented new and useful Improvements in Paper-Registering Instruments, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to the class of paperregistering devices which are designated f point-feed registering instruments, said instruments being equipped with pins or points which engage or enter into slits made inthe paper for that purpose, said adjustment serving to adjust the sheet to its requisite position for being folded or otherwise operated on. The object of our present invention is to provide simple and efficient means for insuring the entrance of the registering-point into the slit of the paper without unduly straining the sheet or incurring liability of tearing it; and to that end the invention consists in the improved construction and combination of parts hereinafter described, and set forth in I the claims.

. said machine.

In the annexed drawings, Figure l is a side elevation of a paper-foldin g machineequipped with our improved registering instruments arranged for registering the sheet longitudinally, some of the minor details of the machine being omitted to avoid obscuring more essential features employed in connection with our invention. Fig. 2 is a plan view of Fig. 3 is an enlarged longitudinal section on line X X in Fig. 2, showing the registering instrument in its operative position. Fig. 4 showssaid instrument in position to allow the paper to be drawn from under it by the folding-rollers drawing the paper down between them, and Fig; 5 shows said instrument lifted to allow the paper to freely pass under it in the process of feedingthe paper into themachine.

Similar letters of reference indicate corresponding parts. A represents the main supporting-frame of a paper-folding machine.

B B denote the folding-rollers; O, the blade which tucks the'paper into the bite of said rollers; a, the traveling tapes which convey the paper into the machine; a, the stationary bars which support the paper beyond the folding-rollers, and D the gage or front stop which arrests the movementof the paper, so as to cause it to lie with its central portion across the folding-rollers. Said sheet delivering and folding devices operate in the usual and well-known manner and are actuated by suitable gearings and mechanism, which are arranged in various ways on different sizes and types of machines and need no special illustration or description in this instance.

0 ur invention resides in the means for registering the paper on the machine preparatory to its being folded or otherwise operated on.

The location of the registering instruments depends on the location of the slits in the paper. In the majority of cases said instruments are required to be located in front of the folding-rollers, as shown in Figs-.1 and 2 of the drawings, in which I) I) represent two soft-rubber-faced rollers disposed beneath the plane of the travel of the paper and justed to proper positions to receive over them the portions of the paper which are provided with the registering-slits.

" By means of suitable gearings rotary motion is transmitted from the driving-shaft b to the shaft 1), as indicated by dotted lines in Fig, 1,0f the drawings, and from the shaft 1) to the nearest folding-roller-Brotary'motion istransmitted by an even numberof gears, as shownin full lines at the top of Fig. 2. of the drawings. V roller rotates reverse from] the roller b," and inasmuch as said folding-roller rotates in a Hence the said folding- IOO shown in Fig. 3 of the drawings.

direction contrary to the feed of the paper the rollers 11 are caused to rotate in the direction of the feed. Over each of the said rollers b b is a rocking arm 0, which moves at properly-timed intervals to and from the periphery of the subjacent roller and is equipped with a point or pin 0 for entering into the slit in the paper lying upon the roller. The two rocking arms 0 c are mounted on a rockshaft 0 to which they are adj ustably secured to allow them to be set into their requisite positions over the rollers Z) Z) and at proper angles to cause the points or pins 0 to be brought to bear 011 the paper with sufficient pressure to subject it to the friction of the rubber faces of the revolving rollers b b and thereby cause the paper to receive a forward impulse, during which the points or pins 0 enter into the slits made in the paper for that purpose. The aforesaid rock-arms require two successive lifts from their depressed positions after the paper has been registered by the pins having entered the slits. The first lift is made to release the paper from the downward pressure of the registering-pins c and to allow the paper to be readily drawn out of engagement with the said pins in the operation of introducing the paper into the bite ofthe folding-rollers B B. The second lift raises the free ends of the rock-arms c a still higher to allow the succeeding sheet to pass freely under the registering-pins c c. This motion of the rock-arms is obtained from a rotary cam F, formed with two steps F F. A rod G has pivoted to it a roller G, which is held in contact with said cam by a springG forcing the rod in opposition to the cam. Said rod thus receives reciprocating motion. A lever II is fastened at one end to the shaft 0 and at the opposite end to the rod G, which latter imparts oscillatory motion to said lever and a corresponding rocking motion to the shaft 0 In order to insure the entries of the regis tering points or pins into the slits in the pa-' per, as aforesaid, we prefer to employ the bridges f f, rising slightly'above the plane of the travel of the paper in proximity to and facing the registering-pins c, as more clearly The slitted portion of the paper is carried onto the tops of the bridges by the time the movement of the paper is arrested by the gage D. This gage then recedes and the registering-pins c are brought down to bear on the paper and by the aid of the bridges open the slits in the paper to facilitate the entrance of the registering-pins during the subsequent movement imparted to the paper by the rollers b b, as hereinafter described.

In connection with the registering instruments located as aforesaid ,we employ an alternately receding and advancing gage D,

- which is connected by adjusting-screws D to blocks D carried on the lower ends of arms D which are fastened in pendent positions to a rock-shaft d, extending across the machine and journaled in posts (1', erected on the sides of the frame A.

The gage D is supported on bars (1 extending from the blocks D and riding with their free ends on rollers (1 pivoted to a shaft d", which extends to the sides of the frame A, where it is suitably supported.

The rock-shaft d is actuated by means of a lever I, fixed to the end of said shaft and having pivoted to its free end a roller 1, by which it bears on a rotary cam I and receives oscillatory motion therefrom. The gage D is provided with screw-threaded hubs D through which the screws D pass, and t0 the outer end of each of said screws is fastened a gear K, which engages a worm-gear K, fastened to a shaft 8, journaled in brackets K formed on the blocks D By turning the shaft 6 the screws D are caused to turn and thereby move the gage D either toward or from the foldingrollers B and thus adjust said gage for different-sized sheets of paper to be folded.

In the operation of the machine the paper is carried into the machine in the usual manner by means of the traveling tapes or a. During this conveyance the rock-arms c are held in their elevated positions and the gage D is in its innermost or advanced position to arrest the movement of the sheet, so as to cause it to lie with its central portion across the folding-rollers B B. Then the gage recedes and the rock-arms c c descend and cause the registering-pins c c to bear 011 the sheet, which is thereby brought into more intimate contact with the rubber-faced peripheries of the revolving rollers 11 b, the frictional hold of which causes the sheet to advance, and in this latter movement of the sheet the registering-pins c 0 enter the slits in the sheet and thereby stop the further advance of the sheet and register the same. The cam F then imparts by its first step a slight lift to the armsc o to relieve the sheet from the pressure of the pins 0 c and allow the. sheet to be readily drawn out of engagement with said pins by the draft of the sheet toward the folding-rollers incident to the introduction of the sheet into the bite of said rollers by the folding-blade O, which operates immediately after the pins do have been lifted as to more positively avoid obstructing the'passage of the next sheet under the pins and to the gage D, which by that time has been advanced to its requisite position for arresting the forward travel of the sheet.

What we claim as our invention is 1. A paper-registering instrument consisting of a rotary roller disposed to receive upon the top of its periphery the slitted portion of the sheet in transit, and a pin or point carried over said roller and to and from the same to enter into. the slit made in the paper for that purpose.

2. A paper-registering instrument comprising a soft-rubberaced roller disposed to re- V ceive upon the top of its periphery the slitted portion of the paper, a registering-pin over said roller and moving intermittently to said roller to press the paper upon it and enter into the slit in the paper, and mechanism imparting motion to said roller and pin.

3. A paper-registering instrument com prising a soft-rubber-faced roller disposed to receive the slitted portion of the paper upon the top of its periphery, a bridge rising from the plane of the travel of the paper adjacent to the aforesaid roller, a registering-pin moving intermittently to the roller to press the paper upon it and in conjunction with the bridge open the slit in the paper preparatory to. the entering of the pin into the slit, and mechanism imparting motion to the said roller and pin, as set forth.

4;, A paper-registering instrument consistin g of a rotary roller provided with a frictionsurface on its peripheryand receiving upon it the slitted portion of the sheet, a rock-arm over said roller moving intermittently toward sheet, as set forth.
